Specification forming part of Letters Patent No. 98,807, dated January1l1870.

To all whom it may concern: i

Beit known that I, GEORGE II. SELLERS, of Wilmington, 4in the county ofNew Castle and State of--Delawara have invented certain new and-usefulImprovements in Roll-Trains for Rolling Metals, of which the followingis a full, clear, and exact description.

In rolling metals into rectangular bars or Vinto irregular shapes, suchas I-beams, channels, Ts, dre., by the methods heretofore einployed, therolls are placed one above the other7 and have their surfaces cut intogroovesy which form counterparts of the finished bars, and are such insize and number as gradually to reduce the shaped pile to the finishedbar. 4'Lhese grooves are frequently-so numerous that two sets of rollsv(one set called roughers7 and itics,'thereby causing the iron, as 4itpasses through the rolls, to slip more or less, and

rendering it liable to be torn or buckled.

For transferring the pile from groove to groove under this system,suspended-hooks are so arranged as to be operated by the work-` man.Vf'.

The object of my invention 1s to diminish the number of groovesheretofore required for. finishing theV shaped bar or beam, and also tosave much-of the handling incident to the system above mentioned; and myimprovement consists, first, in combining, shaping, and compressingrolls with qmechanism whichy renders each roll adjustable' relativelyyto a common axial'line or center, substantially as hereinafter setforth; second, in combining adjustable horizontal shaping-rolls withadjustable vertical compressing-rolls and supporting friction-rolls,both the compressing-rolls and the supportiiig friction-rolls beingmounted in a common adjustable frame arranged between the be'arin oftheshaping-rolls.

In the accompanying drawings, which make other fluid.

part of this speeiication, Figure l represents a plan or top View of somuch of my improved `roll-train as is necessary to exemplify theinvention herein claimed; Fig. 2, a Vertical transverse section throughthe same; Fig.v 3, a view in elevation of the same as seenfrom one end;Fig. 4, a view ofa portion of the mechanism, showing themode ofoounterbalancin g the pistons; Fig. 5, a horizontal transverse sectionthrough the housing at the line A B of Fig. l, and Fig. 6 a similarsection at the line C D of Fig. 3 Fig. 7, a horizontal section throughthe machine at the line rv :v of Fig. 2.

Upon bed-plates a c', solidly secured inany proper well-known way, aremounted vertical housings I) b', which are in turn iirmly united withhorizontal housings@ C'. These housings dift'er from those ordinarilyused in having in place of 4screws for adjusting the rolls cylinderscontaining suitably-packed pistons d, movin g'water-tight in thecylinders and acting on the roll-necks by means of water or Thecylinders are connected by ducts in the housings, or by external pipes,with chambers containing pistons e of smaller area, whose stroke is tothat of the larger pistons as the differences of their areas.

` The upper shaping-rollrG, and the two side compressing-rolls I `If arerespectively counterweigh-'ted by weighted levers f,g Fig. 4, and bear-upon their correspondingV pistons d in such manner that any movement ofthe smaller pistons e would, by `displacing the fluid, cause theircorresponding pistons d to move relatively, thus moving its roll towardor from "the common center and correspondingly increasing or diminishingthe area of the aperture between the rolls through which the pilepasses. In this instance the horizontaler shaping rolls G` G are shownasmounted in strong bearings, adjustable vertically in the housings b.The driving-poweris applied to these rolls in any of the usual wellknownways. The compressing or vertical rolls I I are mounted in bearingsadjustable horizontally in the bea-rings C, and are revolved by frictionupon the pile in. passing through the rolls, the principal function Ot'the vertical rolls being' to prevent the lateral Vspread of the metal.

As the vertical rolls are located between the shaping-rolls, theirbearings are necessarily too shortl to sustain, of themselves alone, thepressure to which they are subjected. To adapt them to sustain thispressure, I support these rolls I I by means of friction-rolls J J whichhave their bearings in the same ad j ustable frames as the rolls I I',and are arranged at such a distance apart that the journals of thehorizontal rolls G G' may' pass between them, thus securing firmbearings for all the rolls. (See Figs. 2 and 7.)

The small pistons c may be connected by the cross-heads H, to whichscrews, racks, and pinions, or other equivalent devices, may beattached, to enable the workmen to operate all the pistonssimultaneously or successively.

The drawings lrepresent a machine having grooved shapingrolls, adaptedto rolling hexagonal bars, the method of doing which is as follows: Thepistons ebeingretraeted by theoperator, 4the rolls are thereby openedand ready to receive the heated pile. The rolls G G being rotated in theproper direction, the pile, whenl placed in the groove, will be drawnthrough between the rolls, the pile itself revolving the rolls I I byfriction. After the pile has been passed through the rolls the workmanforces the small. pistons c into their respective chambers, whichmovement causes the fluid contained in the chambers to force out thelarge pistons d from their chambers, thus causing all the rollssimultaneously to converge toward a common center, and reducing theaperture between the rolls.

The adjustment of either or any of the rolls relatively to the othersmay be regulated independently by adjusting the position of thecorresponding cross-heads, 'and thus increasing or diminishing the'range of movement of the corresponding pistons.

When the rollshave been adjusted and the ,aperture between them thusreduced, their movement is reversed in any well-known Way--l forexample, by simply reversing the engine, or by reversinggear,'and thepile drawn back through the rolls to the side from which it firststarted. This process of diminishing or contractin g the aperturebetween theV rolls and repassing the pile through them from side to sideis repeated until the bar is finished.

After each passage through the rolls the pile is turned so as to presenta new'angle of the hexagon to the action of the shaping-rolls.

By changing the rolls GG for others having grooves of proper outline,I-beams, chair' nels, or other shaped bars may be produced; or forrectangular bars it is only necessary to substitute plane-surfacedshapiiigrolls.

One great advantage of a mill of this construction'is that, as the pile'simply traverses back and forth through the same grooves untilfinished, suspended hooks are dispensed with,

Iprefer the hydraulic arrangement for heavy work, but do not confinemyself to that device v for adjusting the rolls, as they may beregulatedy by screws or other devices.'

, I am aware ythat roll-trains have heretofore been made 'adjustable invarious ways; but such adjustments have always involved a change in the,axial line of movement of the pile or ingot in its passage through therolls. I am, however, not aware that a roll-train ever heretofore hasbeen Vmade so adjustable that all the rolls could be moved toward orfrom each other to vary the area of the opening between them withou'tchanging the axial line of movement of the pile or ingot in its passagethrough the rolls, and this capability of rolling in a const-ant axialline is the distinguishing characteristic of my invention. v y

What I claim as my invention, .and desire to secure by Letters Patent,is-

l. The combination, with the compressing,-

rolls and the shaping-rolls, all having -their axes in the same verticalplane, of n'nechanis'mv to move all of said rollstoward or from acommoncenter or fixed axial line, as andfor the purpose set forth.

2. The combination, with the adjustable horizontal shaping-rolls, of thevertical compressing-rolls and their supporting friction-rolls,thecompressing and friction rolls beinglocated between the bearings ofthe shaping-rolls and mounted in a common adjustable frame,substantially as s et forth.

I testimony whereof I have hereunto subscribed my name.
